Just thought I would share this link. A friend of mine put me onto this great jazz drum app so that bass players and other musicians can practice with real drums. There are hundreds of loops that have been transcribed from specific jazz recordings. each loop has a reference to which recording it was from with the name of drummer and title track added so the original can be traced down. I have just started getting into it and it has already helped my practice sessions and feel.
